Super Duplex S32760 yam ntxwv
Super Duplex stainless hlau S32760 (UNS S32760, DIN 1.4501, ASTM F55) yog tsim los ua Zeron 100 los ntawm UK tuam txhab Mather & Platt hauv xyoo 1970s. Nws muaj me ntsis tooj liab thiab tungsten cov ntsiab lus piv nrog S32750. UNS S32760 muaj 25% chromium, 7% nickel, 3.6% molybdenum nrog rau tooj liab, tungsten, thiab nitrogen. Qhov no yog qib super duplex nrog ferritic -austenitic microstructure. Nws muaj kev tiv thaiv zoo heev rau hauv cheeb tsam corrosion thiab kev ntxhov siab corrosion cracking ua ke nrog cov neeg kho tshuab siab zog.
Stainless hlau qib F55 muaj kev tiv thaiv zoo heev rau ntau qhov chaw, tshwj xeeb tshaj yog tiv taus pitting thiab crevice corrosion nyob rau hauv seawater thiab lwm yam chloride uas muaj ib puag ncig, nrog rau qhov tseem ceeb pitting kub uas yog ntau tshaj 50℃(122℃F). Cov khoom no tau paub tias kuj muaj lub zog siab thiab ntev lub neej. Nws yog 10% sib zog dua qib 316 steel, zoo tagnrho rau sub-xoom kev pabcuam, thiab raug nqi ntau dua li cov nickel alloys. Stainless hlau qib F55 tau yooj yim machined thiab welded.
